CDC Says Pfizer and Moderna COVID-19 Vaccines are 94% Effective Against Hospitalization in Older Adults

On Wednesday, the Centers for Disease Control and Prevention (CDC) published a real-world study that found the Moderna and Pfizer-BioNTech COVID-19 vaccines are 94% effective at preventing hospitalizations among fully vaccinated adults 65 years and older. The study focused on hospitalizations in 24 hospitals across 14 states, and nearly half of the 417 participants were over the age of 75.

“These findings are encouraging and welcome news for the two-thirds of people aged 65 and up who are already fully vaccinated,” said CDC Director Rochelle P. Walensky. According to CDC data, approximately 81% of U.S. adults 65 years and older have received at least one COVID-19 vaccine dose as of Tuesday.
